Part number K536M

STEMCO K536M is cataloged as a QwikKit steering-knuckle kingpin kit with a tapered threaded pin configuration.

Detailed product and selection notes

Exact part is in QwikKit column; no-ream family Do not mislabel PlusKit as a reaming product

This part is listed in the QwikKit catalog column. Family descriptions do not confirm the exact stocked bushing material or transfer another kit’s properties. Confirm the exact axle/application, supplied-kit revision and component list against current installation instructions. Both families are no-ream; this comparison is not an installation procedure, torque specification, performance or warranty guarantee, or universal vehicle-fit statement. Do not select another kit from this family comparison alone. It does not confirm replacement suitability, reverse or multi-part interchange, identical kit contents, or packaging equivalence. The K536M application rows specify special removal tool ST90-1; whether it is included is not established. This is not an installation instruction. OEM SPEC 2.360 x 8.92 differs from dimension-table DIA. 2.441 / LENGTH 8.920; the diameter and measurement basis remain unresolved.

The dimensional table lacks an explicit general inch-unit header; no diameter or length is repeated in the new lead. Family membership alone does not authorize variant interchange or installation.

K536M diameter conflict and special-removal-tool note remain explicitly qualified; no diameter or included-tool inference.
